Abstract

A light source apparatus for endoscope includes: a housing including an intake port; a first heat radiating portion connected to a first light source and cooled by gas taken in from the intake port; a third heat radiating portion connected to a third light source, and cooled by gas taken in from the intake port; and a second heat radiating portion including a lower necessary cooling amount than the first heat radiating portion and the third heat radiating portion connected to a second light source provided in a flow path in which a flow path of the gas that passes through the first heat radiating portion and a flow path of the gas that passes through the third heat radiating portion are merged together, and cooled by merged gas merged on a merged flow path.
